Empire Magnetics Inc.: Dustproof Brushless Motors - DP Frame Size 7.5 (R80 Series)

Dustproof Motors

Many industrial operations involve the use, production or processing of materials in powder form. Motors used in the automation of such processes are prone to failures when particulates migrate into unprotected bearings and motor cavities.

Empire Magnetics dustproof motors survive in environments where other motors fail.

Features include built-in O ring seals that eliminate dust leaks at potential penetration points, motor insulation that allows operating at 145 degrees C, case temperature (185 degrees C winding temperature) and air fittings for pressurization are supplied; pressure rated to 15 psi to lock out contamination.

Empire Magnetics dustproof motors are available in industry standard size 23, 34, 42, and 65 frame sizes. Note where seal housing affect usable shaft length.

For the most unique and demanding applications, dustproof and abrasive dustproof step motors can be combined with the following environmental options: radiation hardened, waterproof and extended temperature.

Brushless Motors

Empire Magnetic's family of dust proof rated motor/resolvers bundled with a drive system are ideal for efficient closed loop motion control applications. Empire Magnetic's brushless motor with a resolver form a single rugged component suitable for hostile environments. Drive electronics can be removed and controlled from a more hospitable location via RS-232.

Motor Features:

These motors can accommodate rapid acceleration and deceleration. The brushless construction is made for reliability. The brushless resolver can be used as the feedback device. There is high torque to inertia ratio and stall torques from 14 to 451 lb-ins. The unique structure allows maximum power ratings, anti cog design and long life bearings.

Frame size selection:

The 7.5 inch square frame brushless motors (R80 series) include motor with continuous output torque ranging from 160 to 400 inch lb. (18 - 46 Nm), or momentary peak torque from 400 to 1000 inch lb. (45 - 113 Nm). Rotor inertia from 15 to 36.7 oz-in2. Continuous output power of 5900 to 7800 watts.

Model #: DP-R84, DP-R86, DP-R88, DP-R8A

Note: Power output is dependent upon cooling capacity of mounting or system.
